I was mistaken; the Swiss do NOT routinely have assault rifles in their home.

Automatic assault weapons are only in the homes of men in the Swiss militia.

First about the Swiss army.http://en.wikipedia.org/wiki/Military_of_SwitzerlandThe Military of Switzerland perform the roles of Switzerland's militia and regular army. Under the country's militia system, professional soldiers constitute about 5 percent of military personnel; the rest are male citizen conscripts 19 to 34 (in some cases up to 50) years old.

The reform "Army XXI" was adopted by popular vote in 2003. It replaced the previous model "Army 95", reducing manpower from 400,000 to about 200,000 personnel,

http://en.wikipedia.org/wiki/Gun_politics_in_SwitzerlandThe Swiss army has long been a militia trained and structured to rapidly respond against foreign aggression. Swiss males grow up expecting to undergo basic military training, usually at age 20 in the Rekrutenschule (German for "recruit school"), the initial boot camp, after which Swiss men remain part of the "militia" in reserve capacity until age 30 (age 34 for officers).Each such individual is required to keep his army-issued personal weapon (the 5.56x45mm Sig 550 rifle for enlisted personnel and/or the 9mm SIG-Sauer P220 semi-automatic pistol for officers, military police, medical and postal personnel) at home.

Thus I would expect about 200,000 full automatic assault weapons in a country of 8 million.
